Pixel 9a

Some recently added CalyxOS features (April Feature update and May Feature update) will be unavailable, because Google’s codebase for the Pixel 9a is older. As such, the Pixel 9a is on a different codebase than our other supported devices, and is therefore missing some of the most recent changes.
We’ve applied all relevant security patches, however, to ensure that the device remains secure.
We anticipate bringing the Pixel 9a up to speed with latest features and Android 16 support in the near future.

CalyxOS installation instructions available at Install on Pixel 9a.

Over-the-air Updates: CalyxOS updates are delivered over-the-air (OTA) automatically, without any manual intervention needed. However, if you'd like to manually update your CalyxOS install, see OTA.
Security Updates: The Pixel 9a, 9 Pro Fold, 9 Pro XL, 9 Pro, 9, 8a, 8 Pro, 8, Fold, Tablet, 7a, 7 Pro, 7, 6a, 6 Pro, 6 contain the full security patch, as they are still being updated by Google.
Security Updates: The Fairphone 5, 4, Motorola moto g 5G - 2024, moto g84 5G, moto g34 and g45 5G stock OS follows a different security update release schedule, which usually lags behind by a month or two compared to Pixels. The CalyxOS releases for it only contain the latest fixes to the open source components, such as the OS code and the Linux kernel. Proprietary components such as the bootloader, modem firmware, and other firmware get updates as soon as the stock OS update is available.
End-of-life: The Motorola moto g52, moto g42, moto g32, Pixel 5a (5G), 4a (5G), 5 are no longer being updated by the manufacturer, so the CalyxOS releases for these devices only contain the fixes to the open source components, such as the OS code and the Linux kernel. Proprietary components such as the bootloader, modem firmware, and other firmware no longer get updates.
